I'm the same exact way, i felt uncomfortable with my PSE nova, could hit my target everytime cause i shot atleast 30 arrows a day for months. But the thought of it being an old bow around all these newer ones and hearing all the talk about "you need this, and you need that" to kill a deer, made me extremely unconfident. But you gotta think, people years ago didn't have all the fancy new things we do these days, and they still kill deer. You'll definatly learn from yer mistakes, thats one thing i can gurantee!

Just stay confident, patient, and as early in said, shoot whenever possible, and i think you should be alright.

GOOD LUCK!
